Equate antiseptic mouthwash uses the same four active ingredients, at the same concentrations, as Listerine Antiseptic. It kills the same bacteria, fights plaque the same way, and costs noticeably less. For most people, it’s a perfectly good mouthwash.
That said, Equate sells several different mouthwash formulas, from antiseptic rinses to fluoride rinses to alcohol-free options. Whether a particular Equate mouthwash is “good” depends on what you’re trying to accomplish with it. Here’s what’s actually in these products and how they stack up.
Equate Antiseptic vs. Listerine: Same Formula
Equate’s antiseptic mouthwash (the one sold as a direct Listerine alternative) contains four germ-killing essential oils: eucalyptol at 0.092%, thymol at 0.064%, methyl salicylate at 0.060%, and menthol at 0.042%. These are the exact same active ingredients, at the exact same percentages, found in Listerine Antiseptic. The FDA requires store-brand products labeled as equivalents to match both the active ingredients and their concentrations, so this isn’t a surprise, but it’s worth confirming.
The inactive ingredients are where small differences show up. Equate’s Spring Mint Antiseptic, for example, contains water, 21.6% alcohol, sorbitol (a sweetener), poloxamer 407 (a surfactant that helps ingredients mix), benzoic acid (a preservative), sodium saccharin, sodium citrate, and food-grade coloring. These are standard mouthwash ingredients. Listerine uses a very similar inactive ingredient list. The practical difference between the two products comes down to slight variations in flavoring, which is purely a matter of personal preference.
The alcohol content (21.6%) is identical to Listerine’s. That’s what creates the intense burning sensation both products are known for. It also means Equate Antiseptic carries the same downsides as Listerine: it can dry out your mouth with heavy use, and the burn can be unpleasant enough that some people avoid rinsing for the full recommended 30 seconds.
What Equate Mouthwash Actually Does
The essential oil formula in Equate’s antiseptic rinse works by disrupting bacterial cell walls. In practical terms, this reduces the amount of plaque that builds up between brushings. The combination of these four oils has decades of clinical data behind it, which is why it remains one of the most widely used mouthwash formulations on the market.
What it does well: kills bacteria that cause bad breath, reduces plaque buildup, and helps prevent gingivitis (early-stage gum disease). What it doesn’t do: whiten teeth, treat advanced gum disease, or replace brushing and flossing. Mouthwash is a supplement to mechanical cleaning, not a substitute.
Equate’s Alcohol-Free Options
Equate also sells alcohol-free mouthwash formulas, some of which use a compound called cetylpyridinium chloride (CPC) instead of essential oils. CPC works differently. It carries a positive electrical charge that binds to the negatively charged surfaces of bacteria, killing them on contact.
Clinical trials have shown that CPC mouthwashes reduce plaque accumulation by roughly 11% to 22% compared to a placebo, depending on the time since rinsing. That’s meaningful, though generally considered slightly less potent than the essential oil formula in head-to-head comparisons. The tradeoff is comfort: alcohol-free CPC rinses don’t burn, making them a better fit if you have a sensitive mouth, dry mouth, or oral sores.
CPC rinses do come with a couple of known side effects. Some users notice a temporary metallic or bitter taste, which goes away after you stop using the product. More notably, prolonged daily use can cause yellowish or brownish staining on teeth and the tongue. This staining is superficial and a dental cleaning can remove it, but it’s worth knowing about before you commit to long-term use.
Equate Fluoride Rinse for Cavity Protection
If your goal is cavity prevention rather than germ-killing, Equate makes a separate anticavity fluoride rinse. This product contains 0.02% sodium fluoride, delivering 0.01% fluoride ion. That’s the standard concentration for over-the-counter daily fluoride rinses and matches what you’d find in ACT or similar name-brand cavity rinses.
Fluoride rinses work by strengthening tooth enamel and making it more resistant to acid attacks from bacteria. They’re especially useful if you’re prone to cavities, wear braces, or have areas of early enamel erosion your dentist has pointed out. Note that a fluoride rinse and an antiseptic rinse serve different purposes. One fights cavities, the other fights plaque and gum disease. Some people use both at different times of day, though you shouldn’t rinse with one immediately after the other since the second rinse washes away the first.
Where Equate Falls Short
The biggest limitation of Equate mouthwash isn’t the formula. It’s the product range. Listerine has expanded into dozens of specialized variants (sensitivity formulas, whitening rinses, enamel-focused options), while Equate’s lineup is narrower. If you want a basic antiseptic, alcohol-free, or fluoride rinse, Equate covers you well. If you’re looking for a more targeted product, you may need to look at name brands or other store brands with broader selections.
Taste is the other common complaint. Even though the active ingredients match, some users find Equate’s flavoring slightly harsher or more artificial than Listerine’s. This is entirely subjective and varies by flavor, but it’s a frequent point in consumer reviews. If the taste bothers you enough that you skip rinsing, that defeats the purpose. Try a smaller bottle first.
Is the Price Difference Worth It?
Equate mouthwash typically costs 30% to 50% less than the equivalent Listerine product. Since the active ingredients are identical in the antiseptic formula and match the standard concentration in the fluoride rinse, you’re paying less for the same functional product. The savings come from lower marketing costs and Walmart’s store-brand pricing model, not from cheaper ingredients.
For a product you use twice a day, every day, that price gap adds up over a year. If you find an Equate flavor you don’t mind, there’s no pharmacological reason to spend more on the name brand.
